reinforcing the pattern of very cold canadian air conditioning dropping down settling all the way into southern california. as this jet stream dip dives south of southern california, that's going to continue to open the door for this cold, dry air which means we'll see chilly temperatures at least until the start of the workweek. hour by hour by 11:00 tonight, you can see we're at or close to freezing in the north and east bay valleys. and by tomorrow morning, mid to upper 20s possible out towards solano county, east bay locations through the tri-valley and also down for areas south of san jose and some low 30s around the north bay. and you can see we'll have clouds passing by for the next two hours. and throughout the day tomorrow, sunshine. so with that very cold start to the morning, even with the mainly clear skies, it's going to be tough to warm up. we'll see highs mostly in the upper 40s do low 50s. around san jose, temperatures close to 30 by the morning, upper 40s closer to morgan hill. east bay, 50s around pleasanton. not a bad day after the chilly morning.
